About the position – Senior Solution Architect, Power

As Senior Solution Architect – Power, you are the technical “go-to” for the electrical power architecture of our data centers. Your focus is on how the entire power chain fits together – from grid connection and utility interface, through MV/LV distribution, generators, UPS and protection, all the way to the IT load – rather than on being the deepest specialist in a single product.

You lead the overall power concepts and redundancy topologies, translate operational and customer requirements into robust designs, and ensure that our solutions balance resilience, safety, energy efficiency and sustainability.

You work closely with our power OEMs, design partners and contractors, answering technical questions, challenging proposals where needed and making sure that the electrical design is robust, buildable and supports our availability and sustainability targets.

You support Project Managers, Site Managers and the Commissioning Manager with clear technical decisions and you are a key point of contact for the customer’s electrical and operations teams.

Typical systems in your scope:

• Utility and grid connection, including HV/MV interface and main substations (with focus on MV/LV architecture within the data center)
• MV and LV switchgear, transformers, distribution boards, busbars and busway systems
• Generators, fuel systems, ATS/STS and associated control and protection schemes
• UPS systems (various topologies), batteries/energy storage, static transfer switches and DC distribution where applicable
• Earthing, bonding, lightning protection and surge protection
• Power protection and selectivity concepts, relays, coordination studies and power quality
• Power monitoring, metering infrastructure and integration with BMS/DCIM/PME
• On-site renewable integration, energy optimisation and flexibility/peak-shaving solutions

Areas of responsibility

Power architecture and design coordination

• Own and maintain the overall power architecture for assigned projects, including single line diagrams, redundancy concepts and main equipment line-up.
• Translate customer and operational requirements into clear power architecture principles and performance criteria (availability, resilience level, fault levels, selectivity, power quality).
• Define and evaluate redundancy topologies (e.g. N, N+1, 2N, distributed redundant) and ensure consistency between conceptual design and detailed design.
• Review and comment on OEM and consultant designs with a focus on interfaces, selectivity, fault levels, operability, maintainability and safety.
• Ensure that power design choices support required resilience levels, operational concepts and sustainability/energy-efficiency targets.

OEM and supplier interaction

• Act as the main day-to-day technical contact for power OEMs (UPS, generators, switchgear, transformers, busway, metering and protection systems).
• Review OEM proposals, technical datasheets, SLDs, protection schemes and integration documents for compliance with EcoDataCenter standards.
• Coordinate technical questions (RFIs) between OEMs, designers, contractors and the EcoDataCenter project team.
• Evaluate technical options, highlight risks and trade-offs, and make recommendations based on reliability, safety, lifecycle cost and energy performance.
• Support commercial discussions with technical input where needed (scope definition, options, value engineering).

Support to projects and site

• Support Project Managers and Site Managers with clear power architecture input to planning, phasing and constructability.
• Participate in key design, constructability and value engineering reviews, bringing an end-to-end power perspective.
• Visit site regularly to walk installations, verify that the electrical design intent is followed and support resolution of issues.
• Provide practical input on installation sequencing, access, switching/operating procedures and maintainability.

Support commissioning and operations

• Support the Commissioning Manager and commissioning engineers in defining test scope for power systems (functional tests, integrated system testing, failure scenarios and black-building tests).
• Interpret commissioning results from a power architecture perspective, including behaviour under fault and failure conditions, switching sequences and resilience performance.
• Clarify design intent during fault-finding and help assess the impact of deviations or changes on availability, safety and compliance.
• Provide technical handover briefings to operations teams regarding power architecture, protection concepts, limitations and key operating principles.

Documentation and standards

• Ensure that key power documents (SLDs, protection philosophies, metering concepts, operating principles) are up to date, consistent and aligned with as-built conditions.
• Contribute to standardising power concepts, design templates and specifications across projects, based on lessons learned.
• Keep an overview of applicable standards and best practices for data center power design, protection and safety.
• Support the development of EcoDataCenter’s internal guidelines for power architecture, energy optimisation and integration of renewables.

Your profile

You are an experienced electrical engineer who understands how a complete data center power chain should be put together. You may have worked for an OEM, consultant, contractor or operator – what matters is that you can see the whole picture and explain it in simple terms.

• Have extensive experience working with electrical power systems in data centers, industrial plants, energy plants or other mission-critical environments.
• Understand how grid connection, generators, UPS, switchgear, PDUs and busways fit together into a coherent and resilient power architecture.
• Can read and challenge single line diagrams, protection coordination studies, load schedules and general arrangements and spot gaps or inconsistencies.
• Have experience designing or reviewing redundancy schemes (N+1, 2N, distributed redundant, catcher systems, etc.).
• Are comfortable speaking with OEM specialists, asking direct questions and pushing back where a solution does not fit the overall architecture or safety/compliance requirements.
• Can translate technical detail into clear recommendations for Project Managers, customers and operations.
• Enjoy being involved both in design meetings and on site, seeing how solutions work in real life.

As a person, you are analytical, structured and straightforward. You like solving problems by talking directly to the people involved, and you keep the end goal in mind: a safe, robust, efficient and operable power system that supports EcoDataCenter’s sustainability ambitions.

Qualifications

• Degree or vocational qualification in electrical engineering, power engineering or similar, or equivalent experience.
• Solid experience with MV/LV power systems in mission-critical or industrial environments; experience with data centers is a strong advantage.
• Practical experience with some of the following: generators, UPS, MV/LV switchgear, PDUs, busways, earthing systems, protection relays, metering and power monitoring systems.
• Ability to read and evaluate single line diagrams, protection coordination studies, load schedules, short-circuit calculations and basic cable sizing outputs.
• Experience interacting with OEMs or external design partners on technical options, deviations, integration and compliance topics.
• Experience with commissioning or power system testing for large electrical installations is a strong advantage.
• Knowledge of Nordic/European electrical standards and utility environments is meriting.
• Good communication skills in English; Swedish is a strong advantage.
• Good knowledge of the Office package; experience with power system analysis tools (e.g. ETAP, PowerFactory or similar) and CAD/BIM tools is an advantage.
